What age defines a person as a juvenile under typical legal standards?

Under typical legal standards, a person is defined as a juvenile if they are under 18 years of age. This age threshold is commonly used in many jurisdictions, establishing the distinction between juvenile and adult status in legal contexts. Being classified as a juvenile generally means that an individual is subject to different legal procedures and protections specifically designed for minors, acknowledging their developmental stage and capacity for rehabilitation.

The juvenile justice system operates with the intent of promoting rehabilitation over punishment, which is a foundational principle in treating minors differently from adults in legal matters. The age of 18 is significant because it typically aligns with the age of majority in many areas, where individuals are granted full legal rights and responsibilities. Thus, defining juveniles as those under 18 allows the justice system to address the unique circumstances and needs of younger individuals.
